3,015 PointsMy solution works, check fails it however.
Trying to pass this Challenge, I submit the attache code, using mehtod chaining, arrow functions etc as we've been learning. The check for my code fails despite it working as expected. What is this challenge looking for if not an answer that reflects the tutorials?
I should point out that I replcaed the code thinking it might be looking for a longhand version of the functions.
const purchaseItems = [
{
name: 'apples',
dept: 'groceries',
price: 2.49
},
{
name: 'bread',
dept: 'groceries',
price: 2.99
},
{
name: 'batteries',
dept: 'electronics',
price: 5.80
},
{
name: 'eggs',
dept: 'groceries',
price: 3.99
},
{
name: 't-shirts',
dept: 'apparel',
price: 9.99
}
];
let groceryTotal;
// groceryTotal should be: 9.47
// Write your code below
groceryTotal = purchaseItems
.filter( item => item.dept === 'groceries' )
.reduce( (total, item) => total + item.price, 0)
.toFixed(2);
console.log(groceryTotal);
//Outputs 9.47 as required

11,772 PointsIt's because of the toFixed(2), this will change the number to be a string.

Martin Coton
3,015 PointsNope, this is the reply I get despite both methods being called, with or without toFixed() :
"Bummer: Both the reduce
and filter
methods have not been called yet"
Seems odd to me.

Zimri Leijen
11,772 Pointsyou sure? I copypasted your code and removed the toFixed(2) and it passed for me.

Martin Coton
3,015 PointsHmm, a browser refresh seems to have sorted it out. Even after removing toFixed(2) it still failed, duimped the session and it does work. sigh time for a coffee I think.
Thanks Zimri
